Question

A company distributes boxes of chocolates with a mixture of creams, toffees and nuts coated in both light and dark chocolates, for a randomly selected box; Finish attempt Let \( X \) and \( Y \) respectively be the proportions of light and dark chocolates that are creams and suppose that the joint density function JDF is given by; \[ F(x, y)=\{0 \leq x \leq 1,0 \leq y \leq 1 \] 0 elsewhere i) Verify that \( f(x, y) \) is a joint probability density function. ( 4 marks) ii) \( P(0<x<y \) ( 3 marks) iii) In Kitale, \( 50 \% \) of the residents read the Daily Nation Newspaper, \( 60 \% \) read the Standard Newspaper and \( 20 \% \) read both papers. What is the probability that a randomly chosen resident reads at least one of the papers? ( 3 marks)

Let \( X \) and \( Y \) respectively be the proportions of light and dark chocolates that are creams and suppose that the joint density function JDF is given by;
\[
F(x, y)=\{0 \leq x \leq 1,0 \leq y \leq 1
\]
0 elsewhere
i) Verify that \( f(x, y) \) is a joint probability density function. ( 4 marks)
ii) \( P(0<x<y \)
